The best way to sell a Grey Sheet formerly SEC Suspended stock is by direct phone call contact with your Broker. Often there are NO BUY restrictions on G.S. stocks which makes selling difficult, but Brokers can make an exception if a buyer and seller are clients of the same Brokerage. Ask the Broker to search for a buyer and keep the Broker on the line until a buyer is found. After 15 minutes or so your Broker will be frustrated if a buyer hasn't been found so keep dropping your price until a buyer is found.
Since there are no bids and no asks, ie., no quotes whatsoever, a seller needs to be ready to offer shares at below the last traded price.
As well, you should use easy to match lots for sale. EG., 10,000 is much easy to match buyer to seller than 10,450; or one million is easier to match buyer to seller than 1,120,000. You would likely end up still owning some shares but you could get out of most of your stock position.
You didn't mention the ticker. If the stock is at .0001 you may ask the Broker to go to the 5th decimal, eg., .00005.
